Sorry Alan, I'm only half following what is going on and I can't help thinking it's all raher more complicated than it needs be. I think the thing that is missing that would make things a lot easier is an ethernet switch, a box that you plug everything into and then anything can talk to anything else. (ish...) An 8 port gigabit switch can be had for less tha £20 (8 ports - room for expansion, gigabit because you can for not that many more pennies).
A gotcha might be how to get internet access connected to the switch. Does the Vodafone WiFi router have an ethernet socket or is it purely wireless? WAN (Wide Area Network - the internet) on 4G and LAN on WiFi? Looks like you have already used a WiFi access point to connect your PC to the Vodfone WiFi router, so that would be a way for getting the internet into the switch. You'd end up with something like:
(Code: used to get a fixed pitch font so things align properly)
I'd use DHCP, server being the one in the Vodafone box and the PC and Blitzortung set as DHCP clients. (Make sure the PC is not acting as a server as well). Yes, there is a small risk that the PC and/or controller may change IP address on a router restart but generally speaking this doesn't happen. The router remembers the previous MAC to IP mapping and issues the same IP to the same MAC.
